TIE-PLATE FOB BAILWAY-TRACK CQFETSTR'UCTIQNS.

Application filed December 1931. Sierra To ail whom it may-concern.-

Be itltnown thatl, WILLIAM iner-Inn a cit zen of the UnitedStates, residing at lPittshurgzh, in'tlie county of Allegheny and State of Pennsylvania;have invented a new and useful Tie.- .Plate for 'lta1lway-'Traclt Constructions, of which the following; 1s a,

such railway'trackg and. to the means em 'ployed in lnsulatlng the track rails.

v One object of my'invention is to; provide a tie "oi-ate of inijrovcd construction having novel neans w ierehy the track rails'are in sulated from the ties and from each other, and-by wh ch the rails are rigidly secured on the tie plates against't-ertical:and transverse movement while permitting lengthwise movement-of the rails on the tie plateand ties.

.einothei' object of this invention isfto pr ride a tie plate having fastening means of improved" construction wherebythe tie plates and rails are secured and held in place on the ties-and by the use of which the insulating medium is easily and quickly applied for use and is maintained in place tov insulatev the'tie plates and track rails Specification of Letters ream.

from theties to which the tails are applied in forming-the railway track.

' till turther'ohjects of the intention will be apparent as the invention is more fully des'" bed hereinafter. I lleIe-rring to the accompanying drawings forming part ofthis specification, Figure l is a sectional elevationshowing one ij'orin of tie plate constructed and arranged and applied for use in accordance withthis ill-- rent-ion Fig. 2. is a longitudinal section of the runs, the section being: taken on theline I ll of-Fig. 1. Fig. .3 is a plan of the tie plate construction illustrated in Figs 1 and 2 Fig. 4 is a se tional elevation similar to that-shown in Fig. 1, showing a modification inthe tie plate and the fastening means employed therewith by means of which the tie plate and track rails are secured in place on the rail ties. Fig. is a longitudinal section taken on the line VV of Fig. 4. Fig. 6 is a plan of the construction shown by Figs. a and Fig. 7 is a sectional elevation similar to those shown in Figs. 1 and 4 showing a elevation on an enlarged am r 1 tron Fi o. $6 2,781.

ine'ans'emp-loyed in the construction shown in Figsj land? Fig. '9 is a longitudinal scale of the keeper shown'in Figs. '1, 7 and 8. Figlf'ld is a sectional-elevation showing a further modi ncation in the construction of-the tieplate and. fastenings by which the. tieplate and track rails are secured to the ties. is a transverse section of the sa1i'1e,-tl1e section being taltenon the line Xl-Xl of 10" Fi is a plan of the construcshown in Figs. 10 and 11.

In thedrawings referring to the conuctic n shown'in Figs. ii, 2 and 3, the track rails A e secnred in place on the tie plates hv means of keepers C engaging with one flange 2 otthe track rails. and rail clips D which engage the opposite flange 3 of the rails-A. Securing bolts-Ll are 6H1:

ployed in rfastening the rail clips D in place 'on the tie plates B and ties E. The-tie plates havea flat web portion 5 with oppositely pro ecting flanges 6,-8, 7, 7 along the marginal edges thereof. The flanges- -6, 6 along one edge are curved inwardly into hooked form,- and theoppositely 'pr-oect1ng flanges 7, Y on the opposite marginal i edge of the web 5 have downwardly and inwardly inclined inner faces 8. The downwardly e-Xtending hook flange 6* on the tie plate B is arranged to engage with the top surface of the metal tie 'E to which it is applied and, the metal tie E has a beveled edge, portion 9 adjacent to the beveled or inclined face 8 on the downwardlyextending flange 7 located ,on the opposite edge portion of the tie plate. A sheet oft-vulcanite, wood fiber, or other suitable insulating material, 10, which is. preferably molded to the desired shape preparatory to being putinto'use, is placed in positionbetween the top surface of the tie E and the under surface of the tie plate 13, so as to insulate the tie plate from the tie. One marginal edge of the insulating material is curved. or bent to conform to the's'hape of the undercut recess formed by the hook flange 6 on thetie plate B. and the opposite marginal edge of the insulating material is' Pa tented supr 22,1913.-

ion

bent so as to extend at substantially the same angle as the inclined races 8- and 9" of the tie Ev and adjacent flange 7. on the tie plate. Registering openings are provided in the top surface of tl e-tie E,-the tie plate B and the rail clip D employed therewith, through which the bolts 4; extend in securing the rail and tie plate to the tie, and a washer 11 formed of insulating material is inserted between the top surface of thelrail clip I) and the metal washer 12 on the bolts 4, so as to insulate the bolt 4 from the tie plate andrail clip. The diameter of the openings in the tie plate and rail clip is somewhat greater than the'diameter of the bolts 1 extending therethrough, and the so-formed an- 'nular space is filled with pitch or similar in:

sulating material. The rail clip D has a lip 13 alongone longitudinal side edge which overlaps the/side edge of the rail flange 3, with which it engages, so as to prevent vertical or sidewise movement of the rails. .The upwardly and inwardly extending hook flange 6 on the opposite side of the tie plate forms a recessed groove for the keeper C, this keeper having a dep'res sion or groove 1; extending lengthwise in its upper surface. The hook flangeo is formed 50 that its toe is curved downwardly to tightly engage the surface ofthe depres-' sion or groove 14 in the top of the keeper B when this keeper is inserted in place. An overhanging lip 15-is provided on the keeper which engages with the rail flange 2 in the same manner as the lip 13 on the rail clip D in maintaining the track rails in place. The ends of the keeper Care ti-, pered, and in forming the tie plates the hook 'ang'es' 6 engaged by' the keepers C are bent 'ownwardly so that the distance between the toei'of' the hook flange and the top surface of the tie plate is slightly less than the thickness through the keeper at points @11- gaged by the toe of the hook flange. This I jconstr uction is clearly shown in F ig. 8. When the keepers C are driven in place the hook flange 6 will be sprung upwardly .Where it contacts with the grooved upper surface of the keeper and the end portions of the flange 6 on account of the resiliency cf the metal of the tie plate will spring downwardly opposite the tapering end portions of the keeper.' T his downward springing of the hooked flange serves to prevent endwise movement of the keeper when inted in place. It will be seen by reference .i ig. 2 that the marginal edges 10" of the ra ts; of the insulation 10 are turned upuardly into contact with the ends of the tie teweb Q'and l1) :i'tcencc to Fig. 3 it i be noted that t e i. sulation 10 is subntially covered and protected from the ither by the metal. or" the track rails, bolt hers and keepers. In the construction shown inFigs. 4, 5

935 and -6, the tie plate B is provided with a down ardly extending flange 7 and hook flange (3,011- opposite side edges ofthe lower surface," of the web members 61" on the tie plate 13 in the same manner as the flanges] 7, 6 in Figs. 1, 2 and. 3. 'Theflangespn the opposite side of the tie. plate are modified to an extent, the hook fiange'ti being arranged so as to engage directly with theflange 2 of the. track rail A, and the keeper cf Figsil, 2 and 3 being dispensed with in 515 this; construction. Instead of employing a I rail clip 'as-in Figsl, 2 and 3, ahook bolt et is used having a lip portion which engages directly with the railflange' 3 in-securingn'the rail in place The head of the hook bolt-P abuts against one side of the upwardly extending flange 7 on'one side edge of the tie plate B The. tie plate 1-3. andv the tie E have registering openings as in the previously described construction and. -a sheet of insulating material 10 similar-to that-before described is inserted between the adjacent faces on the. tie plate and tie. The hook bolt at foi securiiig the rail is insulated from the tie, instead of, as in the construction of Figs. 1, 2 and 3, insulating the se-' curing boltei from the tie plate B andrail A. A washer 16 formed of fiber or other-insulating material in contact with the under surface of the tie E is in turn engaged hya metal .washer 17 which contacts with the spring locking washer 18 shown. when the nut 19 is turned on the bolt 1' to fasten the parts together. In the construction of Figs; 1, 5 and 6, it will be necessary'to back off the nut 19 from the bolt 1 to such extent as will permit sidewise movement of the rail A (from right to left as shown in Fig. i) in removing and replacingthe rails.

In the construction shown in Figs. 1, 2 195 and the bolts 1 securing the rail clip D and the tie plate B to the tie E need not necessarily be removed, the keeper C when removed releasing the rail A and the hook flange 6 being located with respect ,to the marginal edge of the adjacent rail flange 2 so as to permit removal of the rail. In the construction shown in Fig. 7 the. hook bolt l by which the rail A and tie plate B are fastened to the tie E is the same as in Figs. 1, 5 and (3, and the flanges on the bolt side of the tie plate web 5 are also the same as that shown -in Fig. 1. The oppositely projecting hook flanges 6, 6 on the opposite side of the tie plate web are constructed and arranged in the same manner as shown in Figs. 1, 1? and 3. and a keeper C is en'iployed in'this hook flange construction which is fornied as before described in connection with Figs. 1, 2 and 3, 7 and 8.

In the construction shown by Figs. 10 -11 and 12 the tiev plate 13 is disposed with respect to thefrai'lA and tie E in the same manner "as-1m thelpreceding figures. The tie plate hajs4-.-a;, -Web member 5 with oppositely weaves disposed flanges 7, 7 on each of its opposite a side edges, the tie plate of these figures prei v erably being symmetrical about the transversecenterof-the web, A sheetof insulating material 16- is placed between the lower surface of the tie plate web 5 and the top surface of the tie E- and the opposite end portions of the insulation 1% are turned joining faces 8*, 9 of the tie and the downwardly extending flanges 7 on the tie plate. The opposite side edges of the insulating material 10 are turned upward so as to ex- 1 tend betweenand engage with the adjacent side edges of the tie plate web and the upwardly extending flanges on the tie, which projectabove' the upper surface thereof. it- 'rail clip D having a fiange engaging lip 13 is employed to engage with each rail flange 2 and The top surface of these rail clips D is curved as isbest seen in Fig. 10 and the; outer beveled edge engages with the flanges 7 projecting upwardly from the upper surface of the tie plate web 5. The tie plates, tie and rail clips, andwhen employed, the insulating material have open-' ings or holes therein which are in register when assembled, the bolts 4 extending therethro'ugh in securing the several parts'in place upon the tie. The holes through the tie plate are somewhat larger in diameter than the bolts and annular projections 21 on the rail clips D extend downwardly into the holes, these project-ions serving to over- 35 come anytendency of the rail clips to creep and the bolts 4 to melt or tilt on the rail ties when in use. The holesin the ties-and the portions of the bolts therein are elongated or oblong so, as to prevent turningof the bolts in the holes. A metal washer-22 having a curved under face and the spring locking washer 23 and nuts 24:. are employed on the bolts, to hold the rail clips and tie plate on the tie in rail securing posit-ion and a fiber washer 25 is placed between the curved f on the rail clips and the washt the bolt is perfectly insulated y plate and rail clip. To exclude moisture? and more effectively insulate the parts, the annular space between the bolts andsurrounding walls of the holes in the tie late and rail clips arefilled with pitch or similar insulating material.'

The-railztie construction with We T V tie plate and rail fastening desaihed and claimed herein is particularly adapted for use, is fully shown and described in my co pending application Serial No. 6645,7230, tiled Dec. 9, 1911, for railway track constructions, although the insulated tie plate and rail fastening covering the subject matter of this invention can be applied for use to various known metal tie constructions.
